Abstract
A method for forming a semiconductor device includes forming a first gate electrode over a semiconductor substrate, wherein the first gate electrode comprises silicon and forming a second gate electrode over the semiconductor substrate and adjacent the first gate electrode, wherein the second gate electrode comprises silicon. Nanoclusters are present in the first gate electrode. A peripheral transistor area is formed devoid of nanoclusters.
